Theory

Hex letters can be used to write english words, like cafebabe, or deadbeef.
This is handy for developers, because we can put "recognizable text" in binary data.
Unfortunately, there aren't that many words spelled with just the letters a through f.
Using creative (or l337)
spelling, we can expand the list.

Practice

Using an existing list of common words, and a small python program,
I created an 1196-word list of hex words.
